Abstract
The invention relates to parts of a refrigerating compressor and provides a valve plate for a sealed refrigerating compressor cylinder. The valve plate is provided with a base plate, four screw holes are arranged on four corners of the base plate, the base plate is further provided with an air suction hole and an air discharge hole, an air discharge valve sheet is arranged on the back of the base plate, and the air discharge hole is located in the middle of the air discharge valve sheet. The valve plate for the sealed refrigerating compressor cylinder is characterized in that the central line of the air discharge hole and the central line of the air suction hole are located on the same central line of the valve plate, the air suction hole is rectangular, one edge close to the front end of the rectangular air suction hole serves as the long edge, the long edge is arc-shaped, and four corners of the rectangular air suction hole are arc angles. The valve plate for the sealed refrigerating compressor cylinder facilitates smooth air discharge, reduces air discharge pressure loss, simultaneously can increase area of the air suction hole, reduces starting loss of an air suction valve sheet, improves air suction efficiency, and is particularly suitable for air suction and discharge system in a small sealed refrigerating compressor.
Description
(i) technical field: the present invention relates to the refrigeration compressor component, especially a kind of valve plate for sealed refrigeration compressor cylinder.
(ii) background technique: at present, in refrigerator hermetically sealed compressor industry, valve plate is as the closed end of compression cylinder, have a suction port and exhaust port at least, major control flowing to of gas and is flowed out, the suction port of valve plate and suction valve chip form Aspirating valves and are controlling flowing to of air-flow, and valve plate exhaust port and exhaust valve plate, exhaust buffer substrate tablet, exhaust limiting board form the outflow that outlet valve is controlled gas, and the high efficiency of miniaturization sealed refrigeration compressor depends primarily on Aspirating valves and the good performance of outlet valve.Along with the continuous upgrading of country to energy consumption standard, if promote the performance level of compressor by improving Aspirating valves and outlet valve, seem more and more important simultaneously.We know, the size that strengthens suction port can promote gettering efficiency, but traditional valve plate suction port generally is designed to circle, referring to Fig. 1, Fig. 2, the round diameter design is excessive, and corresponding suction valve chip seal section round diameter extends to the bent intermediate section, cause that suction valve chip bending section length shortens, the corresponding increase of width, so just increased the unlatching moment of suction valve chip; On the other hand, the exhaust valve pool passage two side on common valve plate is straight line type, is unfavorable for the smoothness of exhaust.
(iii) summary of the invention: purpose of the present invention will solve exactly traditional valve plate and adopt circular suction port, aperture inconvenience design is excessive, the unlatching loss that affects suction valve chip increases, affect the problems such as the raising of gettering efficiency and exhaust passage fluency be not good, a kind of valve plate for sealed refrigeration compressor cylinder is provided.
Concrete scheme of the present invention is: for existing valve plate, improved, it has substrate, divide four jiaos on substrate and have four screw holes, also have suction port and exhaust port on substrate, have the outlet valve film trap at the back side of substrate, exhaust port is positioned at the middle part of outlet valve film trap, it is characterized in that: described exhaust port center line and suction port center line are to be positioned on the same center line of valve plate; Described suction port is rectangle, and one side of the forward end of rectangular suction port is arc line shaped for ，Gai Chang limit, long limit, and four jiaos of the rectangular suction port is arc round angle.
The long limit of suction port of the present invention and the center line of valve plate are arranged vertically.
Outlet valve film trap of the present invention is arc shaped surface near the side wall sections of exhaust port.
The present invention has the Aspirating valves film trap in the front of substrate, and described exhaust port and suction port all are placed in the Aspirating valves film trap.
The place ahead that the present invention is positioned at suction port on substrate has the installation locating slot.
The present invention has the following advantages:
1. the suction port profile changes rectangular into, can be designed to larger hole area, reduces the cracking pressure loss, improves gettering efficiency;
2. be provided with the circular arc runner in the outlet valve film trap, be beneficial to the exhaust smoothness, reduce the exhaust pressure loss.

(v) embodiment:
Example 1: referring to Fig. 3 .4, structure one of the present invention, be suitable for installing embedded suction valve chip, it has substrate 1, divide four jiaos on substrate 1 and have four screw holes 3, also have suction port 4 and exhaust port 2 on substrate 1, have outlet valve film trap 5 at the back side of substrate 1, exhaust port 2 is positioned at the middle part of outlet valve film trap 5, and have Aspirating valves film trap 7 in the front of substrate 1, described exhaust port 2 and suction port 4 all are placed in Aspirating valves film trap 7, particularly: described exhaust port 2 center lines and suction port 4 center lines are to be positioned on the same center line of valve plate; Described suction port 4 is rectangle, and one side of rectangular suction port 4 forward ends is arc line shaped for ，Gai Chang limit, long limit, and four jiaos of rectangular suction port 4 is arc round angle.
The long limit of suction port described in the present embodiment 4 and the center line of valve plate are arranged vertically.
The film trap of outlet valve described in the present embodiment 5 is arc shaped surface 8 near the side wall sections of exhaust port 2.
The place ahead that is positioned at suction port 4 in the present embodiment on substrate 1 has installs locating slot 6.
Example 2: structure two of the present invention has the basic structure of example 1, different, and in the present embodiment, Aspirating valves film trap 7 is not opened in the front of substrate 1, and referring to Fig. 5, this valve plate is applicable to installing the integrated type suction valve chip.
